fix: actions in slack notification

[vincent-tarrit]

Greptile Summary

This PR fixes broken Slack notification actions in the build error and build success notification flows. The original code used a legacy attachment actions array with a url-based button (type: "button", url: buildLink), which doesn't function without Slack Interactive Components configured on the app. The fix removes the actions block and instead adds a "Details" field using Slack's mrkdwn hyperlink syntax (<url|text>).

• The approach is sound, but the mrkdwn <url|text> syntax in an attachment fields.value requires mrkdwn_in: ["fields"] on the attachment object to be rendered as an actual hyperlink — without it, Slack renders the text literally (e.g. <https://…|View Build Details>), so the link will still not be clickable.
• The bulk of the diff is a whitespace reformatting (tabs → 2-space indentation) across both files; no other logic was changed.

Confidence Score: 3/5

• The fix addresses the right problem but introduces a new rendering issue — the mrkdwn link in field values will render as literal text without mrkdwn_in: ["fields"], so the build link will still not be clickable for Slack users.
• The intent is correct (replacing non-functional interactive actions with a static link), but the replacement will silently produce unformatted literal text in Slack field values. Adding mrkdwn_in: ["fields"] to both attachments is a one-line fix needed before this works as intended.
• Both packages/server/src/utils/notifications/build-error.ts and packages/server/src/utils/notifications/build-success.ts need mrkdwn_in: ["fields"] added to their Slack attachment objects.

mrkdwn link won't render in field values without mrkdwn_in

Slack does not apply mrkdwn formatting to attachment fields.value by default. The <url|text> syntax in value will render as a literal string (e.g. <https://…|View Build Details>) rather than a clickable hyperlink, which is just as broken as the previous approach.

To enable mrkdwn rendering in field values, mrkdwn_in: ["fields"] must be added to the attachment object.

The same issue exists in packages/server/src/utils/notifications/build-success.ts at line 256–260.

That doesn't look necessary.
